@kraftwerkturbo : Sorry, I left the SW out -- Probably the most important detail when talking about eh LS50s! I have dual PSA 1500 crossed over at (i think 100hz).
Don't get me wrong i've been satisfied - more so then ever - with the LS50s in my room. Actually "room" is a bit of a misnomer. My listening area is part of our finished basement and I have about a 15'W x 45'L x 9'H room (but the listening area really occupies 15x25x9 area of the basement). I think I can get more "oomph" with a larger speaker and liked the LS50s so much that I'm already sold on my next kef purchase.
The LS60s are nice and all, but - for me - there might be an interim financial step before I get there. I'd also like to give KEF time to evolve the wireless / powered speaker technology a bit more. Some have suggested the R3s as well and that's a very viable solution. Really, anything in the R line is interesting to me at this point.
